Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the "pay-streak". Pay-streaks always form along the gold path where the river's flow slows down on a large scale during a major flood storm.
A Sizing Tank is essentially a Cooling Tank with the ability to size the product in the process. This sizing is done with the help of a vacuum process that submits the product to a change in atmosphere in the tank to help maintain hollows, roundness, wall thickness, and true sizing.
The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite.
